Clock stops when driving.

[Mike H]

While restoring a 64 230 Sl I sent the clock to Palo Alto and had a quartz movement installed.
The clock worked perfectly for a short time; both while driving and parked.
Now it keeps perfect time only when parked, and stops working when driving.
Thank you for any thoughts,
Mike.

Dear Mike:

Check the quality of the pin connections inside the Bakelite terminal.  Often those cables are about to break.
